WILLIAM PETERS, OF CINCINNATI, OHIO, ASSIGNOR OF ONE-HALF TO THE ALPINESAFE COMPANY, OF SAME PLACE.

PERMU'l'ATlON-LOCK.

SPECIFICATION forming part of Letters Patent No. 384,468, dated June 12,1888. Application filed January 23, 1888. Serial No. 261,572. (Nomodel.)

To all whom it may concern.-

3e it known that I, WILLIAM F. PErERs, a

citlzen of the United States, and a resident of the city of Cincinnati,in the county of Hamilton and State of Ohio, have invented certain newand useful Improvements in Permutation- %locks, of which the followingis a specificaion.

The several features of my invention and the advantages arising fromtheir use, couointly or otherwise, will be apparent from the followingdescription.

In the accompanying drawings,forming part of this specification, Figure1 shows the inside of a safe-door, the lock-case cover being removed.Fig. 2 is an enlarged view of the inmost tumbler and the end of thetumbler-arbor. Fig. 3 is a section taken at the lineman, Fig. 1, and ison a larger scale than Fig. 1. Fig. 4 shows an end elevation of the endof the tumbler-arbor, and also a side elevation of the end portion ofthe said arbor. Fig. 5 is a sectlonal view of the end of thetumbler-arbor, and showing in elevation the side of the plate whichlocks the arbor to the tumblers.

The tumbler-arbor A passes through the door of the safe in the usualway. It is pro vided outside the safe with a settingdial, B, and ahandle, C. Any desired number of tumblers D may be employed, each ofwhich is provided with a tappet, (1, adapted to strike against a similartappet d on the adjoining tumbler or tumblers. The intermediate tumblersare each provided with tappets, one on each face, while the outertumbler has a tappet on its inner face only, thus resembling thetumblers in the ordinary combination-lock. The tappets on theintermediate tumblers are preferably made by putting a short rod througheach tumbler, in such position that it projects from each face.

In my look, as shown, there is no provision made for changing thepositions of the tappets on their respective tumblers, but other meansare provided for changing the combination.. Each tumbler has the usualnotch, d, in its edge, which receives the dog e of the latch lever Ewhen all the notches are properly aligned.

The inmost tumbler D is provided with the hub F, which projects from itsoutside face. The hub F is provided with aseries of diametric slots, f,which receive the flat pin G. The end of the arbor A also has atransverse diametric slot, a, in which the pin or plate G is received.Besides the slot a in the arborjA is a screw-threaded socket, a, intowhich the screw H fits. The arbor A is attached to the tumbler D by thepin G, and the latter is held in its place by the screw H, whose headfits over the pin G when screwed into the socket a. With the parts inthis position a given combination will unlock the safe. To change thiscombination it is only necessary to put the pin G- into other slots fthan it previously occupied. This changes the relation of the dial tothe inmost tumbler D, and in this way changes every number of thecombination. It will be observed that this change can readily beefi'ected without removing the tumblers from the arbor, as the hub isupon the outside face of the inmost tumbler, and it is only necessary toloosen the screw which holds the pin G and place it in the desired notchand secure it again.

bination is especially advantageous, because it effects this objectwithout changing any of the tumblertappets. This is especiallydesirable, because it enables a mere novice to'make the desired change.Furthermore it is unnecessary to provide a number of sockets for eachtumbler-tappet, one only being entirely sufficient. This reduces theprice of the look very considerably,and conduces to its simplicity anddurability.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the arbor A,tumblers provided with tappets, theinmost tumbler being also provided on its outside face with a hub, F,and an adjustable connection between the hub and arbor, substantially asand for the purpose set forth.

In this look the device for changing the com- 2. The combination ofarbor A, provided with tappets, the inmost tumbler being also with slota, tumblers provided with tappets, provided with hub F, having radialslots f, 10 the inmost tumbler being also provided with pin G, and screwH, substantially as and for hub F, having slots ,1, pin G, and means forthe purposes specified.
